E46 M3 valve adjustment

The 333hp 3.2L Inline-6 engine in the E46 M3 uses a valve-train that is a little unusual for most modern day street cars, which, allows for high RPM operation. Utilizing small shims on the top of the valve placed between the rocker arm and the camshaft, highly accurate valve lash adjustment can be made to return it to factory specification. A valve adjustment is a relatively simple process, but it is very tedious, time consuming, and precision is key. few technicians have the patience to do it correctly. Tyspeed has performed countless E46 M3 valve adjustments, and takes pride in making the extra effort to get the valve lash absolutely perfect, leaving your S54 to idle and run like a sewing machine.

Another important service item not to be neglected on your S54 is it’s VANOS or Variable cam timing adjuster mechanism. The VANOS unit on your S54 is a highly complex piece of automotive technology, and neglect and abuse over the years and mileage can leave your s54 chattering, clicking, and generally very noisy. This happens for a few reasons, beginning first with the all important Cam Gear Bolts which are known to break!
